Given the term 3x², select ALL of the like terms listed below. Question 3 options: A.-2x²
atroni [7]

Answer:

A.-2x^2

D.5x^2

E.x^2

Step-by-step explanation:

Like terms must have the same variable, in this case x, and the same exponent, in this case 2. Since the original term is 3x^2, the like terms will be those that contain x^2, regardless of whether their coefficient or sign is different.

Analyzing the options:

A.-2x^2

We have the same variable and the same exponent x^2, so it is a like term.

B. 3x

You have the same variable x but not the same exponent. So it's not a like term of 3x^2

C.3x^3

Same variable x but as in the previous case, the exponent is different, it is a 3 and it should be a 2, so it is not a similar or like term.

D.5x^2

In this option we do have the x^2, so it is a like term of  3x^2

E.x^2

It is also a like term because it contains the x^2.

In summary the like terms are:

A.-2x^2

D.5x^2

E.x^2

A. 86<br> B. 111<br> C. 69<br> D. 71
dangina [55]
All the angles of a triangle add up to 180 degrees. 

30+39+<4= 180

69+<4= 180

Subtract 69 on both sides. 

<4= 111 degrees

<1 and <4 are supplementary and adjacent. They equal 180 degrees as well.

111+<1= 180

<1= 69 degrees

I hope this helps!
